StarCraft MMORPG in Development?

CVG is reporting that Blizzard Entertainment has been developing a StarCraft MMORPG and will finally unveil it on May 19th.
The long-rumoured new instalment of Blizzard's massive StarCraft series is set to be unveiled later this month - and it's another massively-multiplayer online game in the style of World of Warcraft, CVG can reveal.

Well placed US sources have revealed to us that the StarCraft MMO will be unveiled at an upcoming Blizzard event on May 19 in South Korea - the epicentre of the sci-fi RTS series' rabid fandom.

With the crazy success of World of Warcraft, it seems reasonable to think that they would go after the sci-fi gamers too.
